Since you are a mage so you cant really drink strength potion and
hit Josephine, what I do is, as soon as I reach the room, I summon wall
skeleton and steel scorpion, then immediately I climb up the ladder again
leaving my fighters to kill for me. Then, I go down again, continue to
summon more --> dead knights. Steel scorpion really works here! Summon a few
of them would be more than enough.
